A person who has the option of going out with friends but instead makes the bizarre yet conscious decision to remain indoors for the night to indulge in activities involving sweatpants, Funyuns, a High Definition television or all three simultaneously. Many times the subject cannot establish a decent justification for his or her actions (ie. citing poor weather conditions) and instead fumbles with their words and mannerisms, often speaking in senseless sentence fragments and avoiding eye contact entirely. Attempts at pleading with them to “just come” and/or “stop being gay” somehow exponentially worsen the situation and furthers the individual’s unresponsiveness.

Current meaning: It's used to refer to someone you used to be really good friends with, but all your other friends tell you, "dude, that person is a bitch. They're rude." But you just laugh and go, "Oh, no! That's just their sense of humor!" Then one day you open your eyes and go, "Oh my God, they really are a bitch." Then you're never friends with that person again and are probably their enemy.

That girl is a spitch. She was my friend, but she kept telling me I was stupid. What a spitch.
